Design patterns are abstract descriptions of solutions to often recurring problems. They are a means to communicate experience in design. Over the past years, along with the increase in popularity of object-oriented design patterns, some problems with the use of them have been identified. One of these lies in documenting software systems using design patterns. Experience has shown that both in the
The most common PID design methods in industry are based on formulas. This article will present some major advantages of instead using the power of computer based softwares for PID controller design. The Matlab based software used in this work was developed in 2007 and derives robust, IAE minimizing, PID controllers. The experiences of using this software are collected in this article and include
Decision-making in requirements engineering often needs to be done in the presence of uncertainty. Rigorous methods can help to increase the probability of making the most appropriate decisions under the given circumstances. Robustness is a measure for the degree of stability of a solution in case of changes in the problem parameters. This paper presents a method (called DECIDERelease) that applie
Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. petraea (endemic to Sweden and confined to open limestone habitats). The majority of alleles at the investigated allozyme loci are common to the three taxa, but the taxa show significant differences in
Abstract in UndeterminedIn this article we examine the emergence of social worker training in the Nordic countries and discuss the possible effects that the social democratic welfare regime has had on such training. We also discuss the development in recent decades of the academisation of the training and the establishment of social work as a subject of research and teaching. The early history of
